My; invention relates to washing and scrubbing machines and' particularly to that .face of the rug; v

type adapted for the'cleansingof rugs.

The primary. object of my inv ention is to provide a machine so designed as to simulate as nearly as! possiblethe motions and oper- .ations usually employed inwashing r'iigs by the slowv and more tedioushand' method;

Another object is to provide such a ma- :chine Whichis adapted to reciprocate back element. v w

A further object is adjusting the pressure of the" scrubbing and scraping .or wringing elements downwardly" against thesur face of the rug. I i

A still further object-is to provide novel means for rinsing during "the scrubbing operation and .for immediately and automat ically pressing the rinse waterfront sur- Another object is the pi'ovision novel soap container for feeding' the scrubbing brush with a cleansingsolutiong" I l A further object is toiprovideqa carriage mechanism with driving means therefor winch 1s driven from the same sonrce as is the scrubblng velement and which renders the machine practically automaticin its op I eration, thus reducing to a minimum the hand work required in the washingof a rug. i A still further obje'ctis .to provide an in-i clined. supportingbed and; suitable tracks over and upon which thecarriage carrying the Washing apparatus may travel.

-Means are also provided for the proper drainage of the used cleaning solutions.

One further object is to provide means in conjunction with the scraping orwring' ing device which will immediately precede its) operation and tend to iron out the wrinkles and irregularities in the rug.

Other objects and advantagesin details of construction and operation will be apparent as the description proceeds, reference being had to the accompanying drawings wherein like reference numerals indicate like par-ts. I

fAt theup'per end of the platform-1 and at each side thereofare" placed wooden-sup porting blocks 4 suitably secured tothe con- .crete base and provided with drain' troughs 5 in "alignment-'withthe troughs 3 of= the platform.- At a 'point adjacent the lower nd of the platform similar blocks 6 -ar'e also inserted" and are similarlyproVided Figure a detail end view-efthe Ina-- chine partly in'fsecti'on -and*"with;- 'certain-' I igure t is a detail side"-view *1llusti'ating A V fpart of the"driving'mechanism and scruband forth over Ithe surface 'ofjthe' rug-or i I other articles to be cleaned, and which'is provided with power ,dri ving' means 4 both for the reciprocating. part an d the scrubbing with the 'aligned drain troughs 7." The blocks 4 and6 'have-been'specified as being of wood, but it will be'understood' that .this isthe preferred" material only,-fai1d other suitable materials maybe used; Such construction renders it comparatively easy to assemble or dismantle the machine on its platform without destroying the platform.

These "blocks are adapted. to support the four upright posts 8, bolted or otherwise se- {cured rigidly to the blocks as at 9.1 Rail members '10 connect the posts 8 'on" the same side of the platform and' directl above'these' rails are additional rail mem ers'-11 also" runninglongitudinal of the platform and -'securely -mounted between the posts 8.

1 These rails just described form a track and rails 10 and the uppe "of plates 13 and having suitable bearin 'rig'idxwith the shaft 29 an tween the plates 13 as shown with the teeth 12 of the rail 11.

rovided with teeth 12 for a purpose to be escribed.

Mounted upon either side of the rails 10 and 11 are vertical supporting plates 13; Each set of plates is connected together by means of pins 14 extendin laterally between the rails 10 and 11, and t e ins 15 extending-laterallybeneath the ower rail 10.

Ears '16 are-formed upwardly from the uppeit'te'dgesof the plates-13am ins 17 also connect the plate 13 throughsuc ears above the pper'r'ail 11. Rotata ly mounted upon the -pm's 14, 15jand 17 are grooved rollers 18, (fiee'F-ig'ure 3) embracing and riding, upon t e bevelled upper and ower edges of the r bevelled edges "of rails 11. It-will-thus be seen that eachset rovides a slidable supporting meansmova le back and forth upon the rails10 and11..' Y

These sets of plates are rigidly connected primaril bya channeled cross piece 19, shown c early inFi re-2,- and connected at each end with the inner late 13 on either side of the platform. ne of the outer plates 13, as shown clearly inFigure 1, is provided with an outwardly extending orizontal platform 20 upon which is mounted an electric motor or other source of power21. Theshaft 22 of this motor pro ects' inwardly over the top of rail 11 an .beyond fthe inner face of the adjacent inside late- 13. A inion 23 is secured upon the on of this sha and a driving chain 24 connects this pinion, with the gear 25 mountedupon a shaft 26fjext'ending between the two "finside plates ""13 and having suitable bearin therein. Asecond gear 27 is also carri" by this shaft 26 adjacent the gear 25 and is: rotatable therewith. Meshing with the gear 27 is a gear 28 secured to shaft 29.

also extending between the inside plates 13 therein. Also ositioned be- 0 early in Fig- P niQn--30 having en agement e opposite end of the shaft 26 also carries a gear 27" which meshes with the gear 28" carried at this end of the shaft 29. The pinion 30 is also carried at this end of the shaft 29 between the lates 13 and meshes with the adjacent teet 12 of the rail 11.

From the foregoing, it will be understood that upon operation of the motor 21, the shaft '26 will be rotated and such motion im arted to'shaft 29 through'the gears 27 an 28. The inions 30 and 30 being rigid wi'th'the sha t 29 and engaging with the teeth 12 of the rails 11 will cause the carriage comprising the plates 13 and the various connections just described between e-scribed such plates, to travel along the rails. It will be understood that by reversing thedirectionof the motor, the carriage may 'be made to travel back and forth in this man- ..ner. .It will also. be understood that the ratio between the various gears just dey will in practice be such as to impart a slow movement to the carriage.

gear

; Pivoted upon the shafts-26 between the gears 25 and 27 on the one side and just inside the gear 27 on the opposite sideof the carriage, are arms lower ends a shaft 32 see -Fi which is a brus or ot 'er scrub element 33. Each end of this shaft 32 is pro- 31 supporting. at their Q-ep vided with a 2pinion 34 meshi with, the ars 27 and respectively. the pin- 10115 34 are comparatively small with vre- Y spect to the gears 27 and 27, it will be understood that the rotation of the brush 33' will be comparatively fast in relation to th movement of the carriage Also suitably supported by the pivoted arms 31 is a semi-circularsplash guard 35 extending over the upper portion of the brush 33 whereby to prevent the washing solution to be thrown upwardly from the brush. This splash guard'35 extends lengthwise between t e pivoted arms 31, and on its upper side supports a V-shaped ho per or soap container 36 preferabl 'divi ed into compartments 37 into whic the soap or cleaning solution may through the bottom of the hopper and through an opening 37 in the upper surface of the splash guard 35 on to the rotatable brush 33. It will be understood that if a rug narrower than the width of the platform 1 is to be washed, it will be necessarv to fill only so many of the compartments 3( be placed and fed of the hopper as will adequately cover the rug. If esired, some suitable'form of reg ulating means for the hopper 36 may be rovided for adjusting the amount of ow therefrom on to the brush.

As illustrated clearly in Figure 2, the channeled crosspiece 19 extending between the inside plates 13 is provided adjacent each end with rigid upstanding pins 38.. A' second set of upstanding 'pins with the top of the cross piece 19 are positioned just inside the pins 38 and to the top of these pins 39 is secured rigidly a fixed bracket 40, as by bolts or screws 41. -A wrin mg or scra ing device hereinafter calle a scraper and indicated at 42 is made 39, also ri edges thereof cut parallel with the platform 2. The upper side of the scraper 42- is pro vided with upstanding ears or lugs 46 form- 'hand .wheel or grip 51 is secured to the up:

per end of the adjusting screw 50.

From the foregoing, it will be understood that if the adjusting screw 50 isturned to cross piece 19.

the right in Figure 2, the spring 48 will be pressed downwardly under tension, resulting in the resilient forcing downwardly of the scraper 42. Conversely, if the screw 50 is turned in the oppositedirection, the

scraper 42 maybe raised with relation to the The bracket 40 is provided centrally with a forwardly extending arm 52 through the front end of which is suitably threaded an adjusting screw 53 provided with a hand wheel or grip 54 and secured at its lower end to a pin 55, (see Figure 1), rotatably mounted in upstanding ears or bearings 56 on the splash guard 35. By this means, 1t will be apparent that upon adjustment of the screw53, the brush 33, splash guard 35 and soap container 36 may be raised or lowered as desired. In such event, the arms 31 supporting these elements just named will be rocked on' their pivots upon the shaft 26 and the pinions 34 will ride upwardly upon the teeth of the gears 27 and 27".. The swivel connection between the lower end of the adjustin screw 53 and -,the top of the splash guar 35 permits such plvotal movement. v A suitablesource of water'supply may be,

provided adjacent the machine and connect-V ing therewith by the flexible hose 57. The lower end of the'hose 57 is connected to a. pipe 58 suitably supported on one of-the plates 13 as at 59- and provlded w1th.the

' controlling valvef60, As vshown clearly in Figure 5, the lowerend of the pipe 58 0 ns intothe horizontal pipesection 61 exten mg I across the carriage within the channeled cross piece 19.' This pipe 61 is provided with suitable spaced openings through which, the water 61 may be forced out on toithe surface of the rug. Just above the cross piece 19 and the scraper 42, pipe 58 is provided with a T coupling 62 whereby some of r the water may be diverted from pipe 58 forwardly and downwardly just ahead of the scraper 42, through the pipe section 63 into the horizontal. pipe 64 running across the carriage just in front of the scraper 42.

This pipe64 is al@ provided with o enin through which the water may, be force d downwardly into the path of the scraper. This arrangement permits adouble rinsin operation :after the scrubbed operation 0 the brush. The lower edges; of the scraper 42 when pressed into close contact with the rug act to press the water ahead asthe carriage moves over the rug and oil' onto the platform 2 where it drains into a suitable sewer or receptacle.

As illustrated in 42 may carry at each end a bracket 65 on the free ends of which may be journaled a roller 66 which precedes this scraper in its movement in one direction and acts to roll out-the wrinkles which may appear in the .rug.

In Figures 6 and 7, I have shown a modified form of rail construction which. comprises an upper rail 67 provided with teeth 68-on its under sidefor engagement with the pinion 30 carriedi on'theend ofthe shaft 29, and a Iowerrail 68 of channel form, that is, provided with the inturned flanges 69 and 70. The adjacent plate 71 forming one end of the carriage is provided with pins 72 carrying rollers 73 engaging the upper and' lower flanges 69 and 70 on the inside thereof. The plate 71 is also provided with suitable openings 74 across whichare mounted vertical vpins 75 carrying the horizontal rollers 76 engageable with the inner face of the side of the channeled rail 68. This roller arrangement provides a protective guiding means and traveling mechanism for the car- Figure 5., if desired a the I 'front outwardly turned side 45 of the scraper riage. In this case,the gear" 28' meshes with the gears 27 as before, which in turn, meshes with an intermediate gear 77 "which drives the brush pinion 34. 1 The pivoted arm 78 mounted on the shaft 26 corresponds to the arm 31 of Figures 1 and 3. y

It will be understood that similar rail construction is provided on each side of the platform as in the modification first described,van,d as .the parts. on each side are practically the. same, -a duplication is be-- lieved to be unnecessary, and one side only has therefore been shown.

The operation of-niy invention is as v follows I I When it is desired to wash or clean a rug, the operator first operates the adjusting screws 50 and 53 to raise the scraper 42and brush 33 above the platform surface 2; The rug vis then spread flat upon the platform and secured in any suitable manner thereto.

The adjusting screws are again operated to force the brush and the scraperdownwardly .into engagement withthe upper surface of the rug, the water turned on" through the pipes heretofore described and the soap solution or other cleaning material fed from the compartments 37 onto the brush 33. The;

- the pipe 64 is forced on to the motor now being started rapidly revolves the brush 33 and slowly moves the carria e along the rails 10 and 11. By reversing tl ie direction of the motor 21, the carriage may be moved back and forth across the rug as many times as desired. It that directly following the scrubbing operation of the brush, the roller 66 engages the rug and rolls' the surplus cleaning solution ahead of the scraper 42 and also water from rug just in front of one-side of the scraper. The movement of the scraper across the rug,- resilient'ly forced downwardly by the adjusting means above described, pushes the rinse water ahead where it may run off of the rug and drain from the platform through the troughs 3. A. second rinsing operation occurs between the edges of the scraper 42 by means of the pipe 63 forcing fresh clean water on to the rug just in front of the rear side of the scra er 42;

The action 0 the scraper 42 on the rug very closely simulates the action of the hand of an operator scrubbing and rinsing a mg by the hand method. Pressure is exerted downwardly and forwardly as the carriage moves along the rails.

Many changes in details ofconstruction and operation may be made without departing from the scope of my invention. I do not limit myself therefore to the exact form shown other than by the appended claims.
